Bridge strengthening with prestressed CFRP plate
The prestressed CFRP plate reinforcement technology reduces the normal peel force between carbon fiber and concrete components, improves the bond stress distribution, and effectively inhibits bond failure.

The difference between FRP strengthening and bonded steel plate
According to the design of equal strength, the glue dosage of the two schemes is equivalent. The FRP strengthening are much cheaper than the sticky steel plate. The cost of the two schemes is flat when short carbon fiber fabric are taken.

Beam bridge superstructure strengthening
There are several kinds of reinforcement and reconstruction techniques for the upper structure of girder Bridges: the expansion and increase of the original structural member section to improve the strength and stiffness of the original structure;To replace the structure of the original resistance with the new structure;The force system of the original structure is changed to reduce the force of the original structure.The prestressing force is applied to the original structure to improve the force performan

Cause Analysis of Culvert Defects and Reinforcement Treatment
In the construction of highway engineering, in order to make the road smoothly pass through the canal without obstructing the traffic, the drainage channel (through the passage) under the roadbed is built under the subgrade. Through this structure, the water can flow through the underside of the road.
